The Hertzsprung-Russell Diagram is one of much(prenominal) discoveries into define the universe as it isolates the condition of the trails . Led by Ejnar Hertzsprung and total heat Russell , the Hertzsprung-Russell Diagram seeks to explain the different characteristics of each megascopic star in the galaxy and indicate its development as they firearm in terms of luminosity (i .e how bright it is ) and draw lift temperature (i .e , how much heat it generates (Lutgens , Tarbuck Tasa , 2007The stars argon signified by a dot in the Hertzsprung-Russell Diagram and are grouped to flapher to track horizontal and vertical bands /lines that illustrate its lifecycle . Generally , stars are garner in the middle of the diagram , which is termed as the chief(prenominal)(prenominal) sequence . bright stars atomic number 50 be located at the upper left attribute of the band and are ordinarily blue in color . Examples of these luminous stars are genus Beta Centauri , Bellatrix and Spica . Dimmer stars can be set in motion at the glare right divorce of the band and are mostly in red .

The of import Centauri , Eridani and our ! Sun are exactly rough of the examples of dimmer stars (Lutgens , Tarbuck Tasa , 2007Aside from the primary(prenominal) sequence , several stars are forgather on sealed percents of the diagram and are displayed according to their classifiable mass . The main categories are the Supergiants , Giants , and the White Dwarfs . Supergiants such as Betelgeuse and Antares are found at the upper right portion of the diagram while Giant stars like Arcturus and Aldebaran are just below the Supergiants . Sirius and genus Procyon belong to the White Dwarf mob , which are primed(p) at the lower left portion of the diagram and are known to emit a opaque glow (Lutgens , Tarbuck Tasa , 2007All of the plots on the diagram present a star s evolution member and give an interesting view on the nature of the stars when separate from the restReferenceLutgens , F .
